named after a well-known Mexican hat.

This image was taken with the Hubble
Space Telescope, orbiting above the Earth every 90 minutes. The image
shows a large dust lane, visible as a thick dark line running around the
middle of the disk. This dust blocks visible light from the centre of the
galaxy, making the edges appear dark.
